SELF-BINDING HARVESTER.

EBPECEFICATION forming part, of Letters Patent No. 352,677, datedNovember 16, 1886.

Application filed July 11, 1885. Serial No. 171,396. (McdeL) To all whomit may concern.-

Be it known that I, Looms A. Carson, of

Uniontown, in the county of Fayette and State of Pennsylvania. haveinvented a new and Improved Self-Binding Harvester, of which thefollowing is a full, clear, and exact description.

My invention relates to self-binding harvesters of that class in whichthe pressure of the grain on the compressors, as the grain is compactedby the packers on said arms, is utilized, when enough grain has beenpacked for a bundle, to trip the binding devices into action for bindingthe bundle, and also to dis charge the tied bundle of grain from themachine.

The invention consists in certain novel features of construction andcombinations of parts of the harvester, all as hereinafter fullydescribed and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a rear view of part ofa harvester, showing in full lines thetripping mechanism and the mechanism for rotating the compress- .ors todischarge the bound bundle, and also the mechanism for operating theneedle-arm and knotter for binding the bundle. Fig. 2 is a reverse Viewshowing in full lines the coinpresso'rs, the packers, and parts of thetripping and driving mechanism. 'Fig. 3 is a' plan view of the binder,partly in horizontal section; and Figs. 4, 5, 6, 7, 8, aud t) are detailviews of parts of the mechanism.

The letters A A indicate the compressors, against which falls the cutgrain passing into the grain chute or receptacle A' from the car rier orelevator of the harvester, (not shown,) said compressors being mountedrigidly on a shaft, a, and are formed with the oppositelyextending endportions, a a, each of which has a curved edge, a into or against whichthe grain is pressed by the packers B, and an opposite edge portion, a,which, as the shaft to is given ahalf-turn, discharges the last boundbundle and brings the opposite curved edge, a of the compressors intoposition for receiving the grain for the next bundle, as hereinaftermore fully explained.

The compressor-shaft a, is journaled below the floor A of thegrain-chute, which floor is slotted for the passage of the compressors,and also for the passage of the packers B, which latter are connected toopposite cranks on a shaft, b, and to links I), hung loosely on theshaft (1, and so as to be operated continuously in the usual mannerbymeans of a belt, b running to a pulley on the shaft 1) from apulley, bon a shaft, 0, from which the entire binding mechanism receives motion,said shaft 0 being provided outside of the machine-frame with achain-wheel, O, which may receive ro tary motion by means of a pitmam.0"", or by belt connecting it in any approved way with the gearing ofthe harvester.

The central or main compressors, A A, are arranged for operation atopposite sides of the needle-arm D,and as closely as may be thereto, andthe outside compressors, A A, are intended to support the butts andheads of the grain as it is received, packed, bound, and discharged.

The needle-arm D is hung loosely on the compressor-shaft a, and near theshaft is provided with a toothed segment or rack, d,which engages asegmental rack, tl,which is rigid on a shaft, D, which is journaled inthe machineframe below the packer-shaft b and carries rigidly outsidethe frame the crank-arm D", to which is pivoted one end of a rod, D theother end of which is pivoted to a shorter crankarm, E, on the end of ashaft, E, which extends through the rigid arm F, fixed to the frame, andat the other end of which arm F, and directly above the compressors andneedle,

are arranged at G the knotter devices which are operated from or by theshaft E.

The k notter devices will not be herein shown or described, as they formno part of the pres ent invention, and will bethe subject-matter ofanother application for Letters Patent shortly to be made by me, itsufficing here to state that the knotting devices G tie the knot at orimmediately after the point of the needle D is raised to them with theend of the cord.

The relative lengths of the crank-arms D E are such that as thechain-wheel H, which receives continuous motion from thechain-wheel C bymeans of chain-belt H, causes the shaft E to make a complete revolutionby means of clutch devices presently explained, the shaft D will merelybe rocked to cause the needlearm D to rise to and be lowered from theknotter at G by the engagement of the racks d dwith' each other.

The needle-arm D has the usual eye, d, for the passage of the cord, andthe usual guard, d", to separate the'bundle of grain being bound fromthe grain descending the chute A above the needle-arm as the tyingprogresses.

The mechanism for automatically tripping the binding devices into actionis arranged as ,follows: The chain-wheel H is loose on shaft E, andhasan internal gear, h, formed on the inner face of its periphery, and inthe body of the wheel I, which is fast on the shaft E and is placed nextthe wheel H, is j on rnaled ashort shaft, 7;, which carries fixedly atone end the pinion t, which meshes with the internal gear,

of wheel H, and carries fixedly at its other end the clutch-wheeLI,which preferably has diametricallyopposite ratchet-teeth i 7, which areadapted to be engaged by the tooth j of a dog, J,which is pivoted at'to'the inner face of the wheel I, and is forced by a spring, j, held tothis wheel, into contact with the clutchwheel, as in Fig. 6, when thetrip-lever K is not holding the dog J back or away from said wheel I,and against a stop-pin, j, in the wheel, said trip-lever K beingoperated to hold the dog J back,as aforesaid, by'means of a triparm, L,which is fixed to the compressor shaft a, and has opposite ends, Il,which alternately act on the trip-lever, as hereinafter more fullyexplained.

The trip-lever K is pivoted at k to the harvester-frame, and consists oftwo parts, a main part, K, which has an end portion, k, which strikesthe edge j of the dog J to lift its tooth j from the clutch-wheel l, andan elastic or spring part, K which is held by a screw or otherwise tothe part K, and has a stud, h on its outer end, which stud is adapted toenter a notch, '5 in the wheel I when the trip-lever K is moved by thetrip-arm Lagainst the wheel I, and the part K of lever K also has astud, which, as the stud Ir enters the notch i of wheel 1, acts againstthe inclined toej of the dog J, to hold said dog out of engagement withthe clutch-Wheel 1 after it has been disengaged therefrom by the endpart 70 of lever K. (See Figs. 1 and 2.)

The trip-lever K is niade. in the two parts K K to allow its part K toyield as the end k of part K is forced inward by arm L to disengage thedog J from clutch-wheel l as the stud k rides on the periphery of wheelI prior to the springing of said stud into the notch i, as will beunderstood from Fig. 6. A spring, k held to the harvester-frame, acts onthe trip-lever K, after the trip-arm L has been moved from the lever, toswing the studs k k k of the lever away from the dog J and clutchwheel1, to allow the dog to engage the clutchwheel to cause the wheel I andits shaft E to be rotated by and with the wheel H to operate the bindingand discharging mechanism, as hereinafter described, and a stop-pin, k,

limits the throw of the lever K by the spring h and holds the lever inproper position to again be'operated on by' the trip-arm L.

It will be understood that when the binding and discharging mechanismsare not in operation, and the dog J is disengaged from the clutch-wheelI, the latterwill be continuously rotated by the free-running wheelHandgears h i, and when the dog J is allowed to engage the clutch-wheel Ithe wheels H I I and dog J rotate together, and the shaft t" and itspinion 2' and clutch-wheel I then will not rotate independently.

A single shoulder, 1", may be provided on the clutch-wheel I, or morethan two shoulders; but the two shown are at present preferred, as theyinsure almost instant engage mentof the dog J with the clutch-wheel whenthe dog is released from the trip-lever K, the pinion i, which drivesthe clutch-wheel, making about five turns toone turn of the chainwheelH, by whose gear h it is driven.

The trip-arm L is fixed to the compressorshaft a, preferably by beingpassed through said shaft, (see Fig. 8,) and on the shaft is placedloosely by its hub m the pinion M, said hub being notched at m aroundthe trip-arm L, which arm thus is caused to turn the shaft a when thepinion M is turned; and these hubnotches m are wider or longer than thethickness of the trip-arm, so that said arm may be rotated sufficientlywith the shaft a and inde' pendently ofa rotation of pinion M,andagainst the tension of a spring, N, to allow the end of the trip-arm Lto be moved from the trip-lever K, as in Fig. 7, by the pressure of thegrain on the compressors A A, when sufiicient grain shall have beencompressed by the packers B to form a bundle or gavel of proper size inthe chute, and at the same time permit engagement of the clutchmechanism to start the binding devices, as hereinafter more fullyexplained.

The spring N is coiled around the shaft 11,

and enters by its one end,'n, aslot made across the shaft, and bears byits other end, a, on a pin, m, fixed in the pinion M. The tension ofspring N thus controls the pressure at which the compressor-shaft ashall be turned by the compacting of the grain against the compressors,and so as to trip the arm L from lever K at the proper time for startingthe binding mechanism. The tension of the spring N may be regulated asrequired by setting its end 112' against any one of aseries of pins, m,fixed to pinion M, or in any other approved way.

To the harvester-frame, or a gudgeon fixed therein, is journaled apinion, O,which meshes with the pinion M, and has a circumferentialflange, P, which is provided with diametrically-opposite notches 12 intowhich notches alternately a stud, r, on a dog, R, pivoted at r to theharvester-frame, is adapted to be forced by a spring, S, for locking thepinions O M at rest, and thereby holding the compressors A. A at restagainst the pressure of the packers B, as the grain to form a full-sizedbundle is packed against the arms, and until a stud or pin, T, on theinner face of wheel I, strikes the extremity r of the dog R to lift itsstud r'from a notch, 19, just prior to the engagement of the segment ofteeth U on the wheel I with the teeth of the pinion O, to give saidpinion a half-turn, the stud'r meanwhile resting on the periphery of theflange I until the wheel 0 stops after the teeth U have passed, and withthe opposite notch, 1), di' rectly under the stud r of dog R, which studthen is forcedinto the notch by the spring S, to lock the mechanism asbefore.

The continuous operation ofthe mechanism is as follows: WVe will supposethe parts to bein the positions represented in Figs. 1 and 2, with theend Z of trip-arm L holding the stud k of trip-lever K into the notch iof wheel I, to lock said wheel, and the knotter devices at rest, andalso with the stud k of lever K holding the tooth-j of dog J away fromthe clutchwheel I, and with the pinions O M- and the compressors A Aalso held at rest by the dog R, the chain wheel H meanwhile beingrevolved by the belt H in the direction of arrow 1, and the grain beingmeanwhile packed in a gavel against the arms A A by the packers B. "Whensufficient grain has been packed in the grain-chute to form a bundle,the excessive pressure of the grain on the arms A A will turn said armsand their shaft a forward and against the tension of the spring N, so asto trip the end Z of arm L from the end of lever K, and the spring kthen presses the le ver to withdraw its stud k from the notch 11 ofwheel I to allow the wheel to revolve, and simultaneously the studs inIt will be withdrawn from dog J to allow the spring j to force its toothj against one of theshoulders 2" of clutch-wheel l, as in Fig. 7, and soas to start the binding devices by rotating the wheel I and its shaft E.The effect will be to rotate the shaft E and crank-arm E and rock thecrankarm D and its shaft D, so as to raise the needle-arm I), by thesegmental racks d d, to the knotter devices at G, which tie the gavel orbundle and cut the cord or band; and just as the needle arm I) isstarted back from the knotter by the reverse movement of the shaft Dthestud T on the wheel strikes the end 1" of dog R to raise its stud r fromthe notch p of the flange P on pinion O, and the segment of teeth U onwheel I instantly engages the teeth of pinion O, to turn said pinion inthe direction of arrow 2 for a half-revolution, or until the stud 1' ofdog R engages the notch opposite the one it had first rested in. Thishalfturn of the pinion 0 had turned the pinion M and trip-arm L andshaft to in the direction of I arrow 3 for a half-revolution, andthereby had carried the compressors A A around a like distance, so thatthe tied bundle or gavel of grain was discharged by the edges a of thearms, which previously had stood below the floor of the grain-chute, andthe opposite curved edges, (i of the arms now rest and are locked inposition to receive the next gavel of grain, the back movement of theneedle-arm i of wheel I to stop this wheel, as its segmental teeth U hadescaped the teeth of pinion O, and the stud k had engaged the lifterdogJ, and the parts then rest in their first positions until the excessivepressure of the grain on the compressors A A will trip the end Z of thearm L from the lever K to start the binding devices again intooperation, as above de scribed.

But one gavel-compressor may he fixed to the shaft, against which armthe grain may be pressed by the packers B, as will readily beunderstood.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1.
